Groovy expression not working in Interview Scheduled notification for Interviewer

Hello, I was trying to customize the text of the notification that is sent to interviewers when an interview is scheduled (IRC_Intrv_Scheduled_Interviewer) in Alerts Composer. I only added a line in the text message but now the groovy expression is not evaluated properly and instead it gets printed in the notification. I tried undoing my edits and going back to the original text message but it keeps not working.

Does anybody know why this is happening and how I can fix it and restore the original text of the notification?

Thank you,

Elisa
